JACKQETED CAN.

SPECIFICATION forming part of Letters Patent No. 379,757, dated March20, 1888.

Application filed December 19, 1887. Serial No. 258,294.

lb aZZ whom, it may concern:

Be it known that I, O'rro G. B1011, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful In]- provements in Jacketed Cans,of which the following is a specification.

This invention relates to sheet-metal cans having sheet-inetal jackets;and it consists in the construction as hereinafter shown and described,and specifically pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a can with one of myimproved jackets attached thereto. Fig. 2 is a cross-sectional view onthe line 00 as of Fig. 1. Fig. 3 are enlarged sectional detailsillustrating the manner of forming and securing the upper edges of thejacket to the can; and Fig. 4 represents enlarged sections inperspective of the adjacent edges of the jacket and a portion of thecapstrip, illustrating more fully the manner of constructing the jacketand securing it to the can. Figs. 5 and 6 are sectional detailsillustrating modifications in the construction.

A represents the can, which will be constructed in the ordinary manner,except that a crimped groove, a, will be formed around the upper part,just beneath the joint 1), connecting the top to the body of the can, asshown more clearly in the upper section of Fig. 3.

B-represents the sheet-metal jacket, having its upper edge turned overat right angles to the body of the jacket, as shown at d, this turnedover edge being adapted to fit into the crimped groove (1, so that whenpressed around the can the jacket will be retained in place andprevented from being drawn downward off the can or the can from beinglifted outof the jacket. The lower edge of the jacket is crimped beneaththe wooden bottom C to retain the latter in place.

The adjacent edges of the jacket, along where the seam usually occurs,are bent backward, as shown at e in Figs. 2 and 4, and adapted toreceive a cap or lock strip, D, having correspondingly-turned edges 9,the sliding of the lockstrip over the edges 6 firmly and securelyuniting the two edges of the jacket and locking them together, andlocking the jacket upon the can. When placing the (No model.)

jackets upon the can, they are opened out sufficiently to enable theturned-over edge 01 to enter the groove a. A sufficient force is thenbrought to bear upon the jacket to cause the adjacent edges e toapproach each other sufficientl y near to allow the strip D to beslipped over the turned-over edges 6 into the position shown in Figs. 1and 2, when the reaction or outward springing of thejacket will causethe strip to be firmly retained in place without any other fastening. Bythis simple con struction I accomplish several important and novelresults. By forming the groove a beneath the joint I), the latteroverhangs the jacket, as shown, so that any leakage from the spout Awill run down over the outside of the jacket, and will not find its waybetween the jacket and the can. This is a very important feature of myinvention, and is not present in yo any other jacketed can with which Iam acquainted. The manner of uniting the upper rim of the jacket withthe can is also an important feature of my invention, and is very muchmore simple and effective than any con- 5 structed with which I amacquainted. Another-important feature is the manner of uniting andlocking the adjacent edges of the jacket together, as by this simpledevice I not only form a complete and perfect joint between the parts,but this form of joint enables me to readily and quickly remove thejacket from or replace it upon the can, when desired, for repairs or forany other purpose. It is very couvenient in cans of this class to beable to re move and replace the jackets when leaks occur in the cans tofacilitate repairs. It also enables a newjacket to be placed upon canswhen worn out or injured beyond repair.

In Fig. 5 I have shown the crimped part (Z 0 formed into a roll or curl,instead of a mere bend, as in Fig. 3; but the results pro duced are thesame, and the bend and curl are substantial equivalents.

Under some circumstances the channel a 5 might be formed around the canat any point between its top and bottom, as in Fig. 6, so that thejacket would cover only a portion of the can.

Having thus described my invention, what I 10c claim as new is- 1. A canhaving an encircling channel, a,

around the body thereof, incombination with respond with and adapted toinclose the foldeda jacket, D, having a crimped upper edge fitover edgesof said jacket, substantially as and ting into said channel,substantially as and for for the purpose set forth. the purpose setforth. In testimony whereof I have hereunto set my 5 2. A can having anencircling channel hand in the presence of two subscribing wit- 15around the body thereof, and a jacket having a I nesses.
